Ah, the ESO forums - They really just meet my fix for seeing dramazzz these days. Occasionally I find some helpful tips and answers but for the most part they bring out my inner troll and make me want to troll the trolls! (Sorry Fog, I have fed the trolls a few times, LOL).
To answer the question from the OP - yes I will continue to stay subbed for the benefits. I look at this game as a hobby and never have issues with "investing" in my hobby to help sustain it. I am also a major Rose Colored Glasses person and with that being said, I really see ESO staying around for a good long while.
Now in terms of you personally continue to sub, I really think that's something you have to decide. I can give you all the feeds and speeds as to why ESO is the greatest game ever, but in reality its all subjective.
